Abstract
The invention provides an oxidation resistant long-acting mulch film for sugar cane. The film is prepared from the following raw materials by weight percent: 95-99 percent of LLDPE (Linear Load Density Polyethylene) 7042, 0.1-2 percent of antioxidant, 0.01-1 percent of ultraviolet absorbent, 0.05-5 percent of hindered amine light stabilizer and 0.01-0.05 percent of liquid paraffin or vegetable oil; as such additives as the antioxidant, the ultraviolet absorbent and the hindered amine light stabilizer are added in the blown film raw materials of the mulch film, free radicals in the mulch film can be effectively reduced and the overquick oxidation and degradation of the mulch film is restrained, and the oxidation resistance of the produced mulch film is coordinated and exerted jointly by the antioxidant, the ultraviolet absorbent and the hindered amine light stabilizer. The heating temperature during production synthesis of the mulch film is lower than 180 DEG C to prevent the pyrolysis of antioxidant components, and the thickness of the mulch film guarantees the smooth film breaking for seedling emergence of sugar cane seedlings.
Description
Technical field
The present invention relates to plastic material and water-saving agricultural technology field, especially a kind of resistance to oxidation, the long-acting mulch film of the special-purpose resistance to oxidation of radiation-resistant sugarcane.
Background technology
Along with Global warming, the increase of extreme freakish weather frequency, Yunnan cane planting zone seasonal drought has become normality, and the sugarcane district anniversary rainfall of 2009 to 2012 Yunnan is than 2000 young 30%-50%.Yunnan Province's sugarcane district drought resisting has become the work of annual.Mulch film is a kind of drought resisting means of agricultural production of water conservation insulation, and sugarcane field film mulching and planting Yunnan Province pushes open in the sugarcane district comprehensively at present, has played tangible the effect of increasing income.But because sugarcane is the long crop (ripening stage 300-400 days) of a kind of growth cycle, the water consumption consumption is fertile, and continuing in arid needs the anniversary drought-resistant water-preserving under the situation of aggravation, just can guarantee the volume increase of sugarcane stable yields.Therefore need a kind of mulch film that can cover for a long time on producing, and cooperate rational film-mulching technique, reduce the effect that soil water evaporation plays the anniversary drought-resistant water-preserving, guarantee the sugarcane high and stable yields.
The long-lived film of Xiao Shouing by add long-lived master batch in the blown film process, improve the wearing quality of film, but because technology is monopolized by developed country, market value is higher in the market.Long-lived film is mainly used in the canopy film of facility cultivation, such as remunerative crops such as anti-season fruit, vegetables, flowers.Because the cost height, general cash crop growth cycle is short, and the long-lived mulch film that is used for the ground covering is not very general.Sugarcane is as the long crop of a kind of growth cycle, and a kind of long-acting type mulch film that can satisfy the sugarcane production cycle plays obvious effects to the sugarcane combating drought and raising yields.
Summary of the invention
The invention provides the long-acting mulch film of the special-purpose resistance to oxidation of a kind of sugarcane, owing in mulch film blown film raw material, add auxiliary agents such as anti-oxidant, uvioresistant and hindered amine as light stabilizer, can effectively reduce the generation of free radical in the mulch film, suppress the too fast oxidative degradation of mulch film, the oxidation resistent susceptibility of the mulch film of production is mainly coordinated performance jointly by antioxidant, uvioresistant and hindered amine as light stabilizer.In the mulch film production building-up process, Heating temperature should be lower than 180 ℃, prevents the antioxidant component pyrolytic decomposition; The thickness assurance sugarcane seedling mulch film of mulch film rupture of membranes is smoothly emerged.
